It is a very unusual expression even in in Chinese. I even asked one friend from Hunan if the expression was unique to Hunan and she asked me what it meant!
It refers to dishes served over rice or noodles. Those are not particularly common in Hunan, other than as fast food or in canteens.
The menu spiciness scale is something I've seen in British restaurants whether Chinese, Indian or Thai etc. I've never seen it in Asia though, that I recall. The chopped chillies are a Hunan thing. I'm never without a jar of 湖南剁辣椒 (hú nán duò là jiāo), Hunan chopped chilli from Changsha by my side. I'm not sure what cultivar of chilli they use, but I guess local but similar to Thai bird's eye.
